Abstract

In this seminar I will present a novel design methodology for the hardware
implementation of a particular class of vectorial Boolean functions, namely
that of non-linear bijective functions. Instances of this kind are commonly
used as basic building blocks in most symmetric key cryptographic algorithms
and are simply known as substitution boxes (S-boxes). The proposed design
technique is aimed at thwarting a class of side channel attacks against such
cryptographic hardware, which has gained particular relevance in the last
few years, that of differential power analysis (DPA) attacks. An important
aspect of the suggested approach is that the cost of applying the
countermeasure is kept low, in terms of silicon process overheads (only
standard CMOS gates are used), area requirement, average power consumption
and latency, when comparing to other known hardware countermeasures that
work at the logic gate level.
